DESK AND SEAT.

.SPECIFICATION forming part of Letters Patent No. 739,868-, dated September 29, 1903.

Application led October 27. 1902. Serial No. 128,849. (No model.)

T0 a/ZZ whom, t may concern:

Be it known that I, ARCHIBALD C. HENDEa- SON, a citizen of the United States, and a resi-V dent of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Desk and Seat, of which the following is a full, clear, and exact description.

This invention relates to an improvement in desks and seats particularly adapted for use in school-rooms; and the object is to provide a desk and seat so connected and arranged that they may be simultaneously adjusted to'desired heights and to retain their proportionate relations as to height.

Another object is to so mount the seat that in its vertical adjustments itwill be adjusted toward or from a desk in front of it.

Further advantages will appear in the general description.

I will describe a desk and seat embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

. in which similar characters of reference indicate corresponding parts in both the figures. Figure 1 is a side elevation of a combined j desk and scat embodying my invention, and

Fig. 2 is a section on the line @o x of Fig. 1.

The side frames of the desk each comprise a lower member or standard 1 and anupper member 2, designed to slide Von the lower member. The uppermember is provided with a slot 3, through which a clamping-bolt 4 passes, this clampingbolt also passing through an opening in the lower member.

At the upper edge of the member 1 is a narrow rib 5 for engaging in any one of the slots 6, formed in the inner surface of the upper member, so as to prevent any lateral movement of the upper member relatively to the lower member, and these slots are also arranged proportionately with notches in the seat-post, as will be hereinafter described.

The forward edge of the upper member 2 is provided with an inwardly-extending flange 7, movable in a channel 8, formed in the lower member. Forward of the member 1 are seat-supporting posts 9, these posts being connected to said member by the rails 10. The seat 11 has swinging connection with standards 12, mounted to slide on the posts 9. lThe standard 12 is provided with a circular opening in which a circular rib 13 on the front edge of the post engages, and the post is provided with a slot 14,u which receives a clamping-bolt 15, from which a link 16 extends to a connection with a clampingbolt1'7,'passing through an opening in the upper chamber of the desk-frame and movable in a slot 18, formed in the lower member of the frame.

It will be understood that the slot 14 is inclined downward and forward and at a relative angle with the slot 1S which will give the desired ratio between the seat and desk without materially changing the angle of the link 16 or binding thereof, as would be the case were the slot 14 straight, and the front portion of the post 13 is also inclined downward and forward. By inclining the post when the seat is lowered it will be moved forward, so as to be closer to the desk in front of it, thus accommodating it to the size of the scholar. At the upper end of the slot 14 is a horizontally-disposed slot 19, into which the bolt 15 may pass while moving the seat down. One wall of the slot 14 is provided with notches 20 to receive the bolt 15, and these notches are proportionately arranged with the channels 6 in the upper member 2 of the desk.

It is obvious that in the construction shown and described the desk and seat may be raised or lowered and maintain their relative proportions and the back 2l for the seat 11,

secured tothe upper portion of the desk, also maintain its proportionate relationwith 'the seat.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A vertically-adj ustable desk, a support therefor, a verticallyadjustable seat, a support for the seat and swinging link connections between the desk and seat, whereby both may be adjusted together and retain their proportionate relations, substantially as described.

2. A vertically-adjustable desk, supports on which the desk is adjustable, a verticallyadjustable seat, posts on which said seatis mounted to slide, link connections between the seat and the desk, the said posts having downwardly and forwardlyinelined slots, and bolts engaging with the links and passing into said slots, 'the said link being arranged to swing on said bolts during the adjustment.

3. A desk having side frames, comprising lower fixed members, upper members mounted to slide on the lower members, means for clamping the members together, posts forward of the lower members and connected thereto, said posts being provided with downwardly and forwardly inclined slots, standards mounted to slide on the posts, a seat supported on said standards, and swinging link connections between said standards and the upper members of the desk-frames, the bolts passing through said inclined slots, substantially as described.

Lt. In a desk, a side frame comprising a zo lower fixed member having a slot, an upper member movable on the lower member and having a slot, a clamping-bolt passing from the lower member through the slot of the uplper member, a post forward of the desk, a
